Scalp involvement is rarely reported in the literature. In this study, we reported a case of LA over the crown and vertex areas of the scalp. The lesions subsided with topical clobetasol propionate/all-trans retinoic acid compound ointment treatment for 2 months and achieved significant improvement.Keywords: primary cutaneous amyloidosis, lichen amyloidosis, scalp, dermoscopy, androgenetic alopecia, case report
